Application filed June 15,

To all whom it may concern: I Be it known that I, ALEXANDER H; Noon, acitizen of the United States, residing at Kildav, in the county ofHarlan and State of Kentucky, have invented new and useful Improvementsin Rotary Car Tipples, of which the following is a specification.

This invention relates to improvements in rotary tipples or dumps foroverturning mine and ore cars to discharge their contents, and moreespecially to improvements in the mechanism associated witha rotarytipple or car dump to hold the car or cars in the tipple during theoverturning operay tion and to release the empty cars after they havebeen restored to their upright position. To this end there is providedwithin the rotating part of the tipple a pair of horns or stops toengage the cars, together with automatic mechanism operating in themovement of the tipple to withdraw and replace the horns or stops as isrequired for Figure 4 is a transverse vertical section on the line 4l-4eof Figure 3.

Figure 5 is a transverse vertical section on the line 55 of Figure 3.

As shown in said drawings the rotary tipple or car dump comprisesacylindric frame or structure, 10, which is mounted to rotate upon anaxis a little inclined to the horizontal, with rails, 11, inthe lowerpart of the frame to receive the cars, 12, through the higher end of thecylinder and discharge them through its lower end. For purposes f ofbetter illustration the side walls of the cylinder, which prevent thecontents of the cars from being spilled out sidewise, are here omittedas also the mechanism for rotating the cylinder and controlling its movements, all of these parts being made in ac cordance with well-knownprinciples and their particular design or construction not Specificationof Letters Patent.

constituting any part of this invention. The cars enter the cylinderfrom a fixed length of track, 20, and being. unloaded through thedumping operation they leave over another section of track, 21 both ofthese fixed sections as well as the movable section 11 within thecylinder being inclined so that the cars will roll along by gravity.

In the lower part of the cylinder 10 between the two rails 11 andparallel thereto is a shaft, 25,.which is journaled in brack ets, 26,secured to the framing of the cylinder; this shaft extending outward alittle beyond the lower end of the cylinder and carrying at its end afixed crank arm, 27, which projects radially towards the axis of thelarge cylinder 10. At the required distance from the lower end of thecylinder to engage with the front wheels of a car which may enter thetipple, or if more thanone car is taken at a single operation, to engagewith the front wheels of the leading car, as here shown, there aresecured to the two rails 11.

a pair of horns or stops, 30; which latter project upward and arepivoted on horizontal pivots so that their upper ends may be spreadapart to release the car. These horns or stops are made with integralcrank arms, '31, which extend downward and are connected through draglinks, 32, to fixed crank arms, 33, on the shaft 25; so that through therotation of this shaft the two horns or stops 30 are spread apart torelease the cars, or are brought back to their verticalpositions,.according to the direction of rotation of the shaft; There isalso fixed to the shaft 25 a crank arm, 4L0, to which is attached oneend of a spring, 41, and the opposite end of thelatter is hooked intothe end of a threaded eyebolt, 42, which engages in a bracket, d3,secured to the base flange of one of the rails. The spring acts normallyto rotate the shaft 25 in such direction as to bring the horns 30 intotheir upright position where the movementof the parts is arrested by theengagement of the two horns against the heads of the rails as shown inFigure 4. By means of a nut, 45, on the end of the eyebolt 4L2 thetension of the spring may be adjusted, and the crank arm 40 is also madewith a number of openings through it designed for engagement by a pin,46, to secure the spring through a clip, 47, so that the radius of thearm may also be varied for the proper operation of the mechanism.

engaging against the horns.

Between the two rails 21 of the fixed section of track beyond the lowerend of the cylinder 10, and in the vertical plane of the shaft when thecylinder is in its normal position, but a little above the shaft, thereis arranged a second shaft, 50, which is mounted to slide endwise inbrackets, 51. A coiled spring, 53, engaging age 1st one of thesebrackets and against a time collar, 54;, on the shaft acts normally toslide the shaft end- Wise in a direction toward the cylinder 10; and atthe opposite end of the shaft there is pivoted to the track bed anupright extending trigger, 60, which is connected through a pair oflinks, 61, to the end of the shaft; this trigger being adapted forstriking by a car axle passing over it to withdraw the shaft against thepressure of the spring 58. T he length of the shaft 50 is such that thetrigger will be spaced from the end of the cylinder 10 the distance ofthe first axle of a car or cars leaving the tipple when the last axle isjust clear of the horns 80, and the end of the shaft 50 which isadjacent to the cylinder 10 is adapted to extend into the plane ofmovement of the crank arm 27.

The operation of the mechanism is as fol lows:

Assuming that the two horns are in their upright or closed positionthrough the action of the spring 41 upon the shaft 25, a car or cars areallowed to enter the tipple along the track 20 whereupon their movementis arrested by the front pair of wheels The tipple is then operated tooverturn the cars, and upon its return movement, which is indicated bythe curved arrow in Figure 4-. the projecting crank arm 27 on the shaftwill strike against the end of the shaft 50 and throw the horns open.The car or cars will then roll out of the tipple and as soon as the lastaxle has passed the horns 30 the leading axle will strike against thetrigger 60 and side the shaft 50 endwise so that the crank arm 27 cansnap back into its vertical position through the action of the spring41, thus closing the horns again and leaving the mechanism ready for theentry of another car or cars into the tipple. As the successive caraxles pass over the trigger G0 the latter will be pulled down to permitthem to pass, and on each return movement of the trigger to its iuprightposition, under the action of the spring 53, the end of the shaft 50will be arrested against the side face of the crank arm 27 to preventany interference With the overturning niovemoiit of the tip ple. But assoon as the crank arm 27 and the shaft 50 are disengaged by theoperation of the tipple the end of the shaft will slide out intoposition for engagement by the crank arm 2? on the return movement ofthe tipple, as above described.

I claim as my invention:

l. In a car unloading apparatus, the comblnation of a rotatable dumpstructure having rails therein to rece' e a car, a fixed ap proach trackleading thereto, a fixed recciv- 111g track leading therefrom, a movablestop within the rotatable structure to hold a car: said stop adapted tobe relea ed t "iove1nent of the structure fron s overturning position toits normal u it position, a part on the fixed recei Jack, and means forresetting the aid means lng set in operation by contact of a passin carwith the part on the tired track.

2. In a car unloading apparatus. the no bination of a rotatable dumpstru? ing rails therein to receive a car, a approach track leadingthereto, a iii- Gil reeeiving track leading therefrom, a movable stowwithin the rotatable structure, means for yieldingly holding said stopin its set position, said stop adapted to he "elcased through movementof the structure from its overturning position to its normal uprightposition, and a part on the fixed receiving track acting throughengagement by a passing car for permitting the stop to be reset, saidpart on the fixed receiving track being operatively connected to theresetting mechanism.

3. in a car unloading a aratus, the combination. of a rotatable car dumpstructure having an inclined track, fixed inclined approach andreceiving tracks connected therewith, amovable stop within the dumpstructure to hold a car, said stop adapted to be released throughmovement of the structure from an overturning position to its normalupright position, a part on the fixed receiving track, and means iorresetting the stop, said means being set in operation by contact of apassing car with the part on the fixed receiving track.

In witness whereof, I have hereunto subscribed my name this 11th day ofJune, 1917.
